What is antibody testing

Before explaining this method, let’s first understand what antibodies are.

The rapid immunoglobulin M (IgM) test paper developed by Chinese academicians is not only a remedy for false negative sampling, but also a method for detecting antibodies.

After the virus invades the body, it likes to kill directly into the cell and hide in it to copy its offspring crazily.

Of course, before entering the cell, B lymphocytes (a kind of white blood cells) find some viruses. B cells are activated and release a large number of antibodies. These antibodies bind to the virus, make the virus lose its ability to invade, and then phagocytes destroy the virus. We call this process humoral immunity.

The antibody is fast and powerful, but the disadvantage is that it can not enter the cell to kill virus. In short, antibodies can reduce the number of viruses in body fluids and prevent more cells from being infected.

There are 5 kinds of antibodies, namely IgM, IgG, IgA, IgD and IgE, with different characteristics and specialties.

When the body is stimulated by COVID-19, IgM will appear in a week or so. Based on this, by detecting whether the IgM in the human body increases significantly, we can indirectly identify whether the human body is infected or not.

How to use CM nasal swab

Nasopharyngeal swab sampling process

Nasopharyngeal swab sampling process

1. Please keep the subject’s head still and remove the secretions on the surface of the anterior nostril.

2. Use a swab or other tool to measure the distance from the nostril to the root of the ear and mark it with your fingers.

3. Insert the swab gently and slowly through the nasal cavity (if both nostrils need to be collected, another swab should be used).

4. Swab to the finger mark or stay for several seconds after encountering resistance to absorb secretions (generally stay for 15 ~ 30 seconds, and then rotate gently for 3 times).

5. Gently rotate and take out the swab and place it in the virus sampling tube (transport medium); Break the swab tail rod along the breaking point and place it completely in the tube. Tighten the pipe cover.

6. Note the information of the tested person and send it to the laboratory for inspection as soon as possible.

Advantages of CM flocked swab

Brief description: it has outstanding sample collection and release ability, can quickly adsorb micro samples, and has high release efficiency

In order to improve the collection of samples, there are different types of flocking swabs, such as pharyngeal swabs, gene detection swabs, forensic DNA detection swabs, gynecological cervical sampling swabs, microbial sampling swabs, etc. all flocking sampling swabs have clear advantages in many application fields.

Advantage

1.Ergonomic and anatomical design;

In order to improve the comfort of patients and the efficiency of cell sample collection.

2. Improve detection inspiration;

The flocking swab proved that it can quickly elute > 95% of the original samples, and easily improve the detection sensitivity.

3. Easy to collect, break, and then transport;

Open the package, collect the cell sample, and then break the broken point part of the swab into the delivery medium or the test tube provided.

4. Certified free of inhibitors and interference;

The sampling swabs were certified to be free of ribonuclease (RNase), deoxyribonuclease (DNase), human deoxyribonucleic acid, and no PCR inhibitors.

Our flocking swabs are famous for their stable and reliable performance and excellent absorption and elution ability.

nasopharyngeal swabs are different from oropharyngeal swabs

COVID-19 nucleic acid detection specimens

Posted on by

As the northern hemisphere gradually enters the autumn and winter season, the form of the epidemic is still not so easy to control.In order to further improve the positive rate of nucleic acid detection, we will show you the collection methods and notes of nasopharyngeal swabs with simple graphics and pictures.

The biggest difference between nasopharynx swab and oropharyngeal swab is that the sampling position is different. That is, oropharynx and nasopharynx. In clinical trials, the positive rate of nasopharynx is relatively higher than that of oropharynx, but the operation requirements of nasopharynx sampling are relatively high and the action should be relatively gentle. In order to improve the positive rate, these patients may take nasopharyngeal swabs again. Comprehensive judgment can improve the diagnostic rate.

The French epidemic ushered in an inflection point, and current restrictions are not relaxed

At the turning point of the outbreak of covid-19 in France, the current restrictions have not been lifted.

According to thr overseas network, the epidemic situation in France has reached a turning point.

French Prime Minister Fidel Castel introduced the situation of the French epidemic at a press conference on the 12th.

Two weeks later, France formed a new epidemic prevention committee to evaluate the outbreak of the blockade.

At a press conference held at 18:00, French Prime Minister Castel said that some indicators showed that the epidemic situation in France had improved, but it was not suitable to relax restrictions.

According to the report of Figaro newspaper, Castle said the outbreak of COVID-19 had a great impact on human health. Now 1/4 of Frenchmen die in COVID-19. So that all those in need can get treatment.

However, the restart of the blockade has achieved results, and the daily new patient curve slowed down within a week, down by about 16%. That could be the turning point of the outbreak. Next week, the medical system may reach the second peak of the outbreak. After that, the number of hospitalized patients will decrease.

Jean Castel warned that the improvement in current epidemic data should be explained in a “positive and cautious” way. Lifting restrictions is irresponsible.

The current restrictions will be maintained for at least 15 days, including the prohibition of non essential transactions, and the continued closure of restaurants and stadiums.

Castel stressed that the government does not want to repeat the blockade measures for the first outbreak of the epidemic this spring, which has led to the stagnation of the country’s economic, social and educational life.

The results of the second blockade will meet expectations. Next, the government will continue to provide large-scale support to enterprises and job seekers. The solidarity foundation will issue unemployment benefits as soon as possible and extend them after they expire. The university town will also mobilize to help poor students and create 1600 student employment opportunities in November, December and January 2011.

Carry forward the spirit of citizenship and make unremitting efforts during the blockade.

At the same time, the authorities asked the Ministry of the interior to strengthen supervision, especially in major cities such as Paris. The French can spend Christmas and year-end holidays with their families. He stressed that he hopes this rule can reach some strict restrictions. It is impossible to expect dozens of people to get together or hold a large celebration on New Year’s Eve.

At the press conference, French health minister Olivier viran, education minister Branke blanch, labor minister Elizabeth Bruno Bernard and economic minister Bruno lemier attended the press conference.

Olivier walan says the epidemic has improved. For the recently discussed new crown vaccine, he said cautiously that there were not all the data. “We are ready to start vaccination as soon as the vaccine is effective and safe.
